Vacuum means rarefied gas below the local atmospheric condition; Features: Protect the workpiece oxidation and decarbonization; protection of the heating element easily oxidized; reduction of gas within the workpiece; additive is more easily oxidized elements in the melting metals.
1, the vacuum resistance furnace: external thermal vacuum furnace, vacuum furnace heat.
2, carbon tube furnace.
3, vacuum induction furnace.
Vacuum furnace features:
(1) strictly vacuum seal;
(2) The majority of heating and insulation material can only be used in a vacuum;
(3) water-cooling devices, vacuum heat treatment furnace furnace shell, lid, guide do not dispose of electric components (water-cooled electrode), intermediate vacuum insulating door and other components are working in a vacuum, the heated state;
(4) The use of low-voltage and high current;
(5) a high degree of automation.
